properly constructed "and properly constructed mouthpieces areyrelatively expensive and diicult to obtain. Since the socket relceiving'the mouthpiece of a trumpet and cornet are of diiferent sizesand the 4trumpet mouthpiece is considerably longer than the cornetmouthpiece, it would be impoible to transfer a' mouthpiece of theordinary construction from a cornet to a trumpet. It is accordinglynecessary that the player provide two mouthpieces and unless vthesemouthpieces are exact" duplicates, great ditlculty is4 experienced inchanging from one to the other thereof.' It is accordingly an importantobject of my invention to'pro- 'vide a structure such that a mouthpiecewhich will fit in a cornet may be eectively extended and enlarged, sothat it may be em loyed in a trumpet. l further object of the inventionis to improve the structure 'of the mouthpiece so that the productionofthe high and low notes of the range of the instrument is facilitatedand the playing otherwise generally made.

These and other objects I attain by the construction shown in theaccompanying drawings, whereinv for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure 1 is a sideelevation of a mouthpiece constructed in accordance with my inventionshowing the mouthpiece section thereof engaged in the receiving bore ofa cornet tube; Y i

Figure 2 is a similar view showing a complete mouthpiece engaged inthe-tube of a inps ma i ireisane lo tudinalctiona view throughthemouthnpgilece;

Figure 4 is an end elevation thereof.

In accordance with my invention', the

mouthpiece is formed in two separable aec-- tions 10 10 oonin diameter,as indicated at 19, so that the stitutes the actual mouthpiece and isprou vided with a mouthpiece bell 12 and with a tapered portion 13 of asize to properly Y tit within the mouthpiece receiving end of a cornettube 14. The rim of the bell 12 is slightly rounded, as at 15, at itslip en@V` gaging surfaceand from this rim, the walls of the bore of thebell converge inwardly toward the throat 16 with very slight curvature,as indicated at 17. The outer face of the bell is concavely curved, asat 18, so that thewall of this bell, in advance of the throat,

is relatively thin, this combination of curvatures for these surfaceshaving` been found to produce a much clearer note in the use of themouthpiece and to enable the production of high and low notes of theregister with great ease. The throat 16 is preferably about Y fivethirty-Seconds of an inch in diameter and from this throat to thesmaller end of the mouthpiece, the bore increases constantly wall of thesmaller end-of the mouthpiece .at its free end is very thin. A

The section 11 has a bore, the outer end 20 of which is constructed toreceive and closely tit upon the smaller end of the mouthpiece, whilethe outer end of this bore is relatively straight. as indicated at.21.The' exterior of the section 11 is slightly tapered, so that it will fitthe mouthpiece receiving bore at the end of a trumpet tube 22 in suchmanner as to provide the necessary prolongation of the mouthpiece 10when combined therewith. The section 11, if desired, may be left in thebore of the trumpet and the mouthpiece 10 simply removed therefrom andinserted in the cornet when the cornet is to be played. The player isthus free from the diiiculties usually arising from the change ofmouthpieces and is enabled to employ a mouthpiece giving the greatesteiciency to his instruments all the time.

Since the construction hereinbeforeY set forth is capable of a certainrange of change and modification without materially departing from thespiritof the invention, I do not limit-myself to suclllespeciicstructure except as hereinafter clai I claim A pipe section forconverting the type of instruments of analogous character consisting ofa sleeve section having an exterior surface tapered y and providedvvthin the tapered vsurface o-the Ainfiel-mm1 with :m internal borehaving at one end e bere', and theether endfofthewiterior bore taperedsurface, the fapel'ings of the said having a cylindrical surface 'f thesame' surfacee being of the same pitch whereby diameter as the' majorVdimnete;` of the bore 1 a mouthpiece having exterior dilfneil'sonsK of'the mouthpiece. corresponding'with the dimensie'nsef the eX-' Intestimony whereof I hereulita affix my terior surface of the sleeve mayEt snugy signature. f y
